What are Anaerobic Infections?

Anaerobic infections are caused by bacteria that can live in the absence of normal oxygen levels. Often, these infections arise from a puncture wound or damage to an area such as the gums where anaerobic bacteria live in low numbers. The introduction of these bacteria into a warm, low-oxygen environment allows them to grow rapidly. Anaerobic bacteria often are responsible for the classic pus-filled abscess seen from pricking oneself on a thorn or loose nail.

Since these bacteria are often introduced deep under the skin or in areas that are difficult to clean and bandage, anaerobic infections are somewhat more serious than other infections and must be treated swiftly to avoid permanent scarring or damage. Schedule a visit with the veterinarian immediately if your dog has received a puncture wound, injured their gums, or has any sort of boil or abscess.

Anaerobic bacteria pose a particular threat to health in that they are often harder for the body’s immune system to fight, and may colonize wounds that are often more serious (i.e. deep puncture wounds). These bacteria often produce toxins that further accelerate the condition.

Symptoms of Anaerobic Infections in Dogs

  • Red, painful skin around injury site
  • Asymmetric rash around injury site
  • Yellow, white or discolored discharge from injury site
  • Fever
  • Weakness
  • Refusal of food
  • Pain, whining while urinating
  • Cloudy, bloody or foul-smelling urine

If left untreated, an anaerobic infection has all of the right ingredients to lead to shock and in serious cases, death.


Common bacterial species include Bacteroides, Enterococcus, Proteus, and Clostridium.

Causes of Anaerobic Infections in Dogs

  • Bite wound from another dog or wild animal
  • Puncture wound from thorn, nail, glass, etc.
  • Gnawing on sharp bone or object (gum irritation)
  • Improper post-surgery care
  • Urinary tract infection

Diagnosis of Anaerobic Infections in Dogs

Owners who notice their dog has received a bite, puncture wound or trauma to the gums should contact an available veterinarian right away, and if possible note the animal or object that caused the injury. Fever, swelling of the wound site, and reduction in appetite are all possible signs of an anaerobic infection and are cause for a trip to the veterinarian at the earliest opportunity. If a small animal bit your dog, and it is possible for you to safely capture it, do so and bring it to the veterinarian's office. Rabies, while not an anaerobic infection, is a serious concern for animal bites.

A veterinarian will make a physical inspection of the wound site, noting the appearance or discharge of pus as well as redness and/or swelling on-site, and may take a sample of any discharge. Be prepared to give a history of any previous veterinary treatment, as some of the antibiotics commonly prescribed can cause adverse reactions. The veterinarian may culture the discharge to identify the microorganism responsible, or take a blood sample. Blood testing is often helpful in determining the severity of the infection by measuring the levels of white blood cells. Bacterial infections that reach the blood stream are life-threatening and will be detected by this test. Urine testing will also reveal the presence of elevated levels of white blood cells, and if the urinary tract is infected, culturing the bacteria is possible with a sample.

Treatment of Anaerobic Infections in Dogs

The treatment for anaerobic infections is antibiotics, possibly in conjunction with supportive care, such as IV fluids, nutrition or rest. Often, if the infection is severe enough to produce an abscess with the production of pus, surgical intervention will be needed to drain the wound and expose it to oxygen. Sometimes this is as simple as lancing the boil or abscess and cleaning it out with a sterile antiseptic solution. In cases of deeper infections, such as in the uterus or thoracic cavity, a full surgical debridement is needed, where the surgeon will scrape out the dead tissue and clean the area. This may require a general anesthetic, which will allow your dog to sleep painlessly through the surgery. However, general anesthetics can sometimes cause your dog to behave in a confused or abnormal manner for a few days post-surgery.

Recovery of Anaerobic Infections in Dogs

As always, it is essential that owners follow the instructions of the veterinarian regarding post-surgical care and administration of medication. Some medicines are inactivated by others, and so making sure to give the full course of antibiotics as directed (i.e. with food, without food, or at specific times of day) is very important to avoid a relapse of the infection. Surgical dressing should be left in place unless directed by a veterinarian to remove them, and a ‘cone’ or other protective device used to prevent the dog from chewing on the dressing. Do not bathe your dog unless directed otherwise after major surgery, as even the cleanest water can introduce new bacteria to an already-weakened immune system.

Anaerobic Infections Questions and Advice from Veterinary Professionals

German Shepherd

Moderate condition

Has Symptoms

Bloody diarrhea, weakness, wt loss

Medication Used


My two year old German Shepherd male received four routine vaccines in one day. Within 24 hours, he developed bright red liquid diarrhea. I brought him to my vet and he was given IV fluids, labwork, abd U/S, amoxicillin and flagyl and a low fat diet. He was diagnosed w/acute pancreatitis and SIBO. He continued with intermittent bloody diarrhea. I came across an article about SIBO in GSDs with the tx being tylosin.
My vet did some research and decided to give tylosin a try. It worked! The dosage was 1/4 tsp powder in food once daily. His bloody diarrhea episodes became less frequent and eventually stopped.

We’re happy that the use of tylosin has helped Mac and that the frequency of bloody diarrhoea has come to a stop. Tylosin-responsive diarrhoea can be difficult to diagnose and may not be clear what the underlying cause is (not always small intestinal bacterial overgrowth). It is great when people share their experiences especially when there is a happy ending. Regards Dr Callum Turner DVM

Laziness and food refusal.

Medication Used

Amoxicillin metrolag

My dog has an infection in the upper tissue of the month which prevents him from eating. The vet prescribed 2 different types of antibiotics. One is amoxicillin and the other is metrolag. How long does it take for him to recover? He is not eating so how can I give him the antibiotics?

The problem here is getting Snowy to take the medication, it may be just a case of having to physically push the tablets to the back of the throat then hold the mouth closed and elevated whilst rubbing the throat to induce swallowing (many videos on youtube about this). You should start seeing improvement within a week or so, but if the infection is severe or resistant or amoxicillin or metronidazole then a culture and sensitivity test may be required.

How much do the anabiotics cost for your dog? Are there different kind so of anabiotics? She doesn't have big symptoms. The anabiotics probably will help her, greatly. She always acts odd. She's a great but strange dog at times.

There are many different causes of weakness and not all of them are infection; plus the use of antibiotics are by Veterinary prescription and would require a visit to a Veterinarian which may cost $50-$90 for a consultation plus any tests and then the cost of treatment on top which depending on the underlying cause may cost anywhere from a few dollars to much more. Antibiotics need to be used responsibly and a given by prescription; there are different types of antibiotics and groups of antibiotics which are given depending on the nature of the infection. Please take Willow to a Veterinarian. Regards Dr Callum Turner DVM
